How do brokers manage B-book risk with AI?
Brokers manage B-book risk with AI across three moves: per-client markout modelling that quantifies expected P&L on holding vs hedging, dynamic routing thresholds tuned continuously against session evidence, and multi-asset exposure alerting with anomaly detection specific to the firm's historical volatility. Every routing decision remains dealer-approvable and audit-logged.

B-book is a portfolio, not a bucket
The mistake most brokers make with B-book risk is treating it as a bucket — 'this client is B-book, that one is A-book' — instead of a portfolio. In a portfolio view, every client × instrument × context combination has an expected markout, and the routing decision is a live optimisation, not a static tag.
AI is what makes the portfolio view operational. A firm-specific model estimates expected markout continuously; the routing engine applies dynamic thresholds; the dealer copilot surfaces the outliers with reasoning.

Isn't B-book just about accepting losing traders?
That is the naive framing. Modern B-book is a live portfolio management problem where AI produces the input the dealer optimises.
Does this work with A/B hybrid models?
Yes — the portfolio framing extends naturally to A/B/hybrid routing.
Compliance posture?
Stronger than manual. Every routing decision documented with reasoning.

Does the model learn our book?
Yes — the model is firm-specific by design, updated on session evidence.
B-book risk is where the modern retail broker's most differentiated P&L lives. AI is what makes it operational.
